Now we only need easy self-hosted Postgres clustering for HA. Postgres seems to need additional tooling. There is Patroni, which doesn't provide container images. There is Spilo, which provides Postgres images with Patroni, but they are not really maintained. There is a timescaledb-ha image with Patroni, but no documentation how to use it. It seems the only easy way for hosting a Postgres cluster is to use CloudNativePG, but that requires k8s.

It would be awesome to have easy clustering directly built-in. Similar to MongoDB, where you tell the primary instance to use a replica set, then simply connect two secondaries to primary, done.

Postgres is not a CP database, and even with synchronous replication, it can lose writes during network partitions. It would not pass the Jepsen test suite.

This is very hard to fix and requires significant architectural changes (like Yugabyte or Neon have done).

Argument is that partitioning almost never happens, because of network reliably rerouting traffic.
